Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years, it has also […]

The mineral processing industry has commonly utilized hydraulic separators throughout history for classification and gravity concentration of various minerals. More commonly referred to as hindered-bed or fluidized-bed separators, these units make use of differential particle settling rates to segregate particles according to shape, size, and/or density. Conventional hindered-bed separators are inherently inefficient due to wide […]

All living organisms respire using diffusion to exchange gases with their surroundings. The systems these organisms utilise in order to survive differ greatly from species to species depending on their structure and habitat. These organisms have evolved over time to occupy these differing habitats, resulting in the need to physically adapt in order to survive […]

According to some societies, all the affairs of life are supposed to be under the control of spirits, each ruling a certain “element” or even object, and themselves in subjection to a greater spirit. [6] For example, the Inuit are said to believe in spirits of the sea, earth and sky, the winds, the clouds […]

Living organisms have a range of macromolecules, including carbohydrates, lipids, proteins, and nucleic acids. These macromolecules are made up of multiple molecules and have various roles such as energy storage and information transmission. While some foods contain mixtures of macromolecules that can be tasted, others cannot be identified by taste alone. As a result, scientists […]

Chemistry has had a huge impact in our society, as it is the basis to a lot of products and knowledge we now have of chemicals around us everywhere. Chemistry has given us knowledge of the chemicals we come into contact with everyday explanation of how they are good or bad to the human body. […]

Spoilage is the process in which food deteriorates to the point in which it is not edible to humans or its quality of edibility becomes reduced.

1. SME is in fact a plant made product (emulsion matrix) which need only to be sensitized by entrapment of gas bubbles either by, chemical gassing or addition of substantial quantity of porous ammonium nitrate (AN) prills, to form explosive. 2. SMS is truly a Site Mixed Slurry explosive in the sense that all intermediate […]

Step 1: gather the ingredients such as water, flour, baking powder, sugar and chocolate icing. The ingredients represent each products that the cycle of photosynthesis need. Such as water – which is use in the light dependent reaction when the molecules splits and gives off oxygen. Step 2: Preheat the oven at 375 degrees and […]

Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five-carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. […]

Effect of Temperature For some substances to dissolve in a given solvent, heat is absorbed. The reaction is endothermic. In this case, an increase in temperature increases solubility. For some substances, heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case, an increase in temperature decreases solubility. […]

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You […]
